Over the past few days, Donald Trump’s former Chief of Staff Reince Priebus and his former Press Secretary Sean Spicer have held day-long meetings with Special Counsel Robert Mueller, suggesting that both former advisers may have flipped on him in the Trump-Russia scandal. It took Trump a minute, but he finally seemed to figure it out this morning – and the result was a berserk meltdown related to the obstruction charges in question.

Mueller interviewed Priebus and Spicer about their roles in helping Donald Trump to obstruct justice, with regard to covering up Donald Trump Jr’s Russia meeting, and with regard to FBI Director James Comey’s firing. Trump seemed to finally put the latter together this morning, and it clearly worried him, as he launched into an unhinged fictional assertion that Comey was somehow scheming to exonerate Hillary Clinton.

Here’s what Trump tweeted this morning: “Wow, FBI confirms report that James Comey drafted letter exonerating Crooked Hillary Clinton long before investigation was complete. Many people not interviewed, including Clinton herself. Comey stated under oath that he didn’t do this-obviously a fix? Where is Justice Dept?” Then he got confused and tweeted something about taxes. Then he finished his Comey thought: “As it has turned out, James Comey lied and leaked and totally protected Hillary Clinton. He was the best thing that ever happened to her!”

This reveals a profound lack of understanding on Trump’s part as to how these kinds of investigations work. By the time Comey had interviewed most of Clinton’s underlings, he already knew she was innocent, and the final interviews were a formality. That’s in contrast to the investigation into Trump, in which his own underlings appear to have already given him up on his crimes. In any case, it’s clear Trump has concluded that he’s going down for firing Comey, and that Priebus and Spicer have done him in.
